WALL-MOLD.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed September 15, 1915. Serial No. 50,792.

To all whom it may concern:

Be it known that 1, ROBERT WILSON, a subject of the King of GreatBritain, residing at 116 Collins street, Hobart, in the State ofTasmania, Commonwealth of Aus tralia, contractor, have invented certainnew and useful Improvements in all-Molds, of which the following is aspecification.

My invention relates to the building of concrete structures such asdwellings, stores, workshops, and the like and provides means wherebyeither solid or hollow concrete walls can be built up section bysection.

According to this invention, a plurality of angle and T irons areemployed, the angle irons, for the most part, horizontally, and the Tirons vertically. Suitable means are used for keeping the framework inposition, and supporting means are provided on the vertical irons forholding specially prepared sheeting frames which, by means of thesupports, can be quickly placed in posi tion and easily removed afterthe concrete has set. But in order to fully understand the inventionreference will now. be made to the accompanying drawings, in which-Figure 1 is an elevation of the suggested arrangement of angle irons atthe intersection of two walls. Fig. 2 is a sectional plan showing angleof wall. Fig. 3 is a side elevation of-a wall frame work with thesheeting frames in position at the base of same. Fig. 4 shows themethods of attaching a T iron to the horizontal angle irons. Fig. 5illustrates a corner angle fixing with brackets for holding sheetingframe. Fig. 6. is an elevation of inside corner showing sheetingbrackets and scafiold rod attachment. Fig. 7 is a sectional plan of a Tiron showing the same. Fig. 8 shows in side elevation portion ofsheeting frame. Fig. 9 is a sectional plan of a T iron showing method ofattaching sheeting frame to same. Fig. 10 is a perspective view of ayoke for supporting the sheeting frames when subjected to pressure. Fig.11 is a like view of a cavity box with lid and stiflener and means forbreaking down the box for removal, and Fig. 12 is a sectional sideelevation of the breaking down means. Fig. 13 shows trough or hopperused for filling cavity Walls, and Fig. 1 1 is a perspective view ofsame with yoke attachment.

The angle irons 15 are laid horizontally in lengths, clamped or boltedtogether if necessary, and riding on the upturned web of same are the Tirons 16 at suitable intervals, the other ends of the same being securedto further angle irons 17 parallel with 15, or to other suitablesupports.

It is necessary, in a structure of the kind lndlcated, to provide meansfor staying the partsend strengthening the whole before applying it tothe use for which it is intended. To that end, the ends of the T ironsare rabbeted at 18 (as shown in Figs. 1 and 4) to rest astride the iron15, and when the iron 17 is placed on the T it can be held by the clamp19. Goose necks 20 are used as struts, the hooks engaging in brackets 21each of which is made of a piece of angle iron packed out from the mainiron by blocks 22. These blocks are used on the upright T and angleirons as seen in Figs. 6, 7, and 9, and are used to support the lugs 'ofthe sheeting frame hereinafter to be described. The blocks should be oflesser area than the iron angle pieces forming the brackets.

The packed out brackets 21 are positioned at intervals along theuprights for the purpose above explained and in order to furtherstabilize the framework riding pieces and other like distance pieces 23are disposed between points in the same.

The open spaces between the upright T irons are filled with the sheetingframes 24: to which is riveted sheet iron to form a plane surface. Thecorners of the frame are provided with lugs or projections 25 which arebent to come behind the cross piece of the T iron and to rest upon theblock 22 thus permitting the sheeting to be flush with the T iron face.To keep the frame in position wedges 26 are driven in between the framelug and the angle iron bracket. The sheeting is suitably reinforced towithstand inside pressure such as by riveting thereto light angle ironpieces 27 both horizontally and vertically if necessary. The length ofthe sheeting frames will correspond with the distance between theuprights between which the frames will be placed longitudr nally andsecured, thus forming a continuous channel having its sides parallel between the uprights into which the concrete is filled, as in Fig. 2, toform a solid wall.

When a hollow wall is to be constructed, as seen in plan also in Fig. 2,cavity boxes 28 are disposed medially parallel to the sheeting prior tofilling in the material through the hopper 29 in the opening of which isa longitudinal convex cap piece 30 that will cover up the box 28 anddeflect the stuff to the sides as it falls through the hopper.

The boxes 28 are specially constructed to facilitate their being removedafter the cement has set and same are provided with lid 31 andstiffening means 31 to avoid the sides bellying under the pressure ofthe material. Each box is made in two or more parts and may have itsedges rolled over as at 32 to assist in withdrawing it. If it is made upof three parts one end of the box is cut vertically and the edges madeto overlap (Figs. 11 and 12), and in order'to strengthen said end a yoke33 is placed over the top edges of the overlapping side and a stirrup34, bent at the top to provide a handle or grip, is adapted to confinethe sides at the bottom. To remove a cavity box it may be lifted bodilyout of place or the grip 34 can be pressed downward and the yoke 33taken out when the sides of the box will collapse inward. Or, if theyoke be removed the sides will collapse and the end with the rollededges may then be lifted clear. If necessary both ends of the box can befitted with the yoke and stirrup device and have the overlapping edges.

The sheeting frames are installed right along the line of wall to beconstructed and receive the wet concrete which is well rammed down. henset the sheeting frames are removed by knocking out the wedges 26 andlifting the frames clear; they are then secured by the wedges higher upthe uprights in the specially devised brackets 21. A yoke 35 may, ifnecessary, be placed over the sheeting frame 24 to steady same underpressure of the wet concrete.

A supply of angle and T irons in different lengths will be kept on handand arranged and disposed according to the ground plan of the structureto be erected. The T irons might be long enough to reach to the top ofthe ground floor rooms, and when the material has been filled in and setto the upper ends of the irons, the latter and the horizontal irons areremoved and relaid upon the set concrete for the purpose of building onto the same another section or lift to the building, and so on until itis raised to the height required.

Having now described my invention what I claim as new and desire tosecure by Letters Patent is 1. In a wall mold, the combination withhorizontal ground irons, and standards supported thereon, of brackets atintervals along said standards, said brackets comprising an angle ironpiece and blocks between each angle iron piece and the standardgoose-necks provided with hooked ends adapted to enter the space formedbetween the angle iron piece and the standard forming struts, and moldpanels supported by the brackets.

2. In a wall mold, the combination with horizontal irons, and standardssupported thereon, of brackets placed at intervals along the standards,said bracketsconsisting of short angle iron pieces, blocks between theangle iron pieces and the standards, said blocks being of lesser areathan the angle iron pieces, panels between the standards and supportedby the brackets, lugs on said panels, and wedges driven between the lugsand the angle iron pieces.

3. In a wall mold, horizontal ground irons, a web on each ground iron,standards upon said ground irons said standards being rabbeted in theirlower ends to take into the web of the ground irons, short angle ironpieces secured at intervals to the standards and packed out from thesame, mold panels supported on the angle iron pieces, distance piecesbetween the horizontal irons, and goose-necks having one end hooked intothe space between the angle iron pieces and the standards and the othersecured to the ground work to form struts.

In testimony whereof I have affixed my signature in presence of twowitnesses.
